Exhaust suggestions
I’ve got a new to me 79 L82. It’s currently in the shop as I wanted a thorough go through of it since it was sitting a lot for a few years. While it’s in I thought maybe I’d upgrade the stock exhaust system (in good condition) upgraded to a true dual exhaust. I simply had in mind keeping stock headers and just bring the duals straight back (eliminating the cat) and installing two high flow mufflers. My mechanic said it would cost about 1500?! He keeps insisting a SS system. Does this sound right? Are there any more reasonably priced dual exhaust suggestions for this C3?

That sounds like a pretty good deal for a custom full stainless system. I got my exhaust for my 79 from corvette central. Pre-pandemic it was a 1k plus shipping. Had to grind on one of the header flanges to clear the Temp sensor port in the head. Other than that it was an easy fit

Anyone have experience with this one? Made for L82.

I have a 78 L82 4spd and bought this system from Corvette Central. They have magnaflow mufflers. A change to true duals you will also need to buy a center hanging bracket. Had them for 12 years now.

Back in the early 90's I purchased a "aluminized steel". Chambered exhaust made by walker. True duels.
Still in great shape. Stainless is overkill. And Stainless tends to crack.
Just another opinion.

System has been great. Installed it myself without a lift & took longer but not difficult. . Might be too loud for some.

I used the Corvette Central system with the Magnaflows on my '80. The system is very nice. I had no issues with fitment and the magnaflows had a nice tone. I did end up changing the Magnaflows for something more aggressive, but the Magnaflows are a nice sounding muffler and they may be exactly what you are looking for. I just wanted something a bit louder when cruising around and at idle.

Thanks. What did you swap out the magnaflows for? Flowmasters?

I fitted Pypes Street Pro chambered mufflers and an X-pipe on my '81 and it's the perfect blend of sounding muscular, but without being obnoxiously loud....

I got the mufflers from eBay... https://www.ebay.co.uk/itm/164565666388
They're stainless and really nice quality.
I bought a locally made X-pipe of which there are are thousands to choose from, but here it is laid out for mock up on the lawn.

Just for info, my system is (was) a true dual, 2.5" which joins to the original 2" down pipes and standard exhaust manifold. The rest of my car is bone stock.
It doesn't drone either and I can have a normal conversation inside.
Best of luck.
Oh, and here's another clip of me driving up the street on very light throttle....

here's one for $65... https://www.ebay.com/itm/25564047601...oAAOSwLv9i2bQH
In the grand scheme of things, they're cheap in my opinion, given how much they change the character of the car.
